ROTARY EN G|N E.

SPECIFICATION forming part of Letters Patent No. 264,507, dated September 19, 1882.

Application filed May 26, 1882.

To all whom it may concern Be it known that I, lsAAo W. BAILEY, of Fairport, Northumberland county, State of Virginia, have invented certain new and useful Improvements in Rotary Engines; and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being bad to the accompanying drawings, in which- Figure l is a side elevation of the device; Fig. 2, a section on the line 00; Fig. 3, a top plan, and Fig. 4 a perspective of the pistondisk.

Myinvention relates to that class of engines consisting essentially of a rotary disk having peripheral pistons adapted to turn within a steam-trunk having suitable steam and exhaust pipes and it consists in certain features of construction and combinations of parts, as hereinafter set forth and claimed.

In the drawings, A is the steam-trunk, haviug steam-chests a,.provided with inlet-pipes B, leading from the boiler.

G is the piston-disk, which is channeled on each side of its center for a part of its circumference, the channels 0 extending rather more than half-way around the periphery of the disk and ending in abutments or pistons c. Inclines 0'! lead from the periphery of the piston to the bases of the channels 0.

Between the steam-chests and the pistondisk are chambers '5, within which are mounted on pivots I the valves 41. The inner faces of the valves are curved to correspond with the curvature of the periphery of the disk, and the ends of the chambers '5 are curved about their pivots I as a center, so that the ends of the rods f F, which are pivoted to alever, e, mounted (No model.)

in bearings E at the top of the trunk A. Exhaust-ports it lead from the inner periphery of the trunk A and deliver at its sides through casings H, in which slides a pair of valves connected by a rod, 9, which latter is connected with the lever e, as shown in Fig. 1, the same construction being duplicated on theopposite side of the trunk A.

In operation, as the lever e is raised at, say, the left-hand end in the figures, the valve J is raised so as to open the lower port in the chest at, and the upper exhaust-port, h, is opened. The lower exhaust-port and upper port are opened at the sametime on the opposite side. The steam entering the chambers i, tilts the valves i, as shown, and the steam, pressing upon the abutments or pistons 0, causes the disk to revolve, the steam behind the valves being exhausted through the ports h. On reversing the motion of the lever e steam is delivered into the other ends of the chambers i, and the other exhaust-ports are opened, reversingthe engine.

Having thus described my invention, what I claim as new,- and desire to secure by Letters Patent, is-

1. In combination with the piston-disk and pivoted reversing-valves, the lever c and connecting-rodsf G, forsimultaneously actuating the steam-inlet valves and exhaust-valves, as set forth.

2. In combination with the piston-disk and steam-trunk, the pivoted reversing-valves i, located on opposite sides of the disk and on opposite sides of itsvertical central plane, the slide-valves J, lever e, and rodsconnectin g said lever with the inlet and exhaust valves, as set forth. Y
